The pathogenic mechanisms underlying Batten disease are unclear. Patients uniformly possess autoantibodies against glutamic acid decarboxylase (GAD) that are predominantly reactive with a region of GAD (amino acids 1 to 20) distinct from subjects with autoimmune type 1 diabetes or stiff-person syndrome. Batten patients did not possess autoantibodies against(More)
Patients and a mouse model of Batten disease, the juvenile form of neuronal ceroid lipofuscinosis (JNCL), raise autoantibodies against GAD65 and other brain-directed antigens. Here we investigate the adaptive component of the neuroimmune response. Cln3(-/-) mice have autoantibodies to GAD65 in their cerebrospinal fluid and elevated levels of brain bound(More)
Btn2p, a novel cytosolic coiled-coil protein in Saccharomyces cerevisiae, was previously shown to interact with and to be necessary for the correct localization of Rhb1p, a regulator of arginine uptake, and Yif1p, a Golgi protein. We now report the biochemical and physical interactions of Btn2p with Ist2p, a plasma membrane protein that is thought to have a(More)
The neuronal ceroid lipofuscinoses (NCLs) are the most common neurodegenerative disorders of childhood. We have examined mRNA levels of the CLN1, CLN2, and CLN3 genes, which are associated with the infantile, late infantile, and juvenile forms of NCL in 64 different human tissues, and have grouped the results into gastrointestinal tract, central nervous(More)
BACKGROUND The 'two-faced' character of reactive oxygen species (ROS) plays an important role in cancer biology by acting both as secondary messengers in intracellular signaling cascades and sustaining the oncogenic phenotype of cancer cells, while on the other hand, it triggers an oxidative assault that causes a redox imbalance translating into an(More)
—In this paper, an attempt has been made to design a low-cost noncontact capacitance-type level sensor for a conducting liquid. The sensor is in the form of a uniform circular cylinder made of insulating material like glass, ceramic, plastic, etc. The sensor is connected with the metallic-or nonmetallic-type liquid storage tank, in which the conducting(More)
PURPOSE Juvenile neuronal ceroid lipofuscinosis (JNCL or Batten Disease) is one of the most common progressive neurodegenerative disorders of childhood, resulting from autosomal recessive inheritance of mutations in the CLN3 gene. Pathologically, Batten disease is characterized by lysosomal storage of autofluorescent material in all tissue types. Although(More)
Breast cancer is considered as an increasing major life-threatening concern among the malignancies encountered globally in females. Traditional therapy is far from satisfactory due to drug resistance and various side effects, thus a search for complementary/alternative medicines from natural sources with lesser side effects is being emphasized.
